Position Summary & Responsibilities

Overview

We are seeking a Application Engineer to join our global infrastructure and platform engineering team, helping build software-driven automation for InterSystems Kubernetes-based managed services and SaaS platforms.

You will work with software engineers, Kubernetes architects, DevOps, SRE, and security teams to develop reliable, secure, production-ready platform capabilities. The role combines Go development with hands-on Kubernetes experience, with a focus on turning repeatable operational processes into maintainable platform software.

Key Responsibilities

Develop and maintain Kubernetes-native software in Go, including controllers, Custom Resource Definitions (CRDs), reconciliation logic, and automation components.
Build automation for provisioning, configuration, upgrades, scaling, recovery, and other managed service workflows.
Write maintainable Go code and develop unit, integration, and cluster-based tests.
Support CI/CD pipelines for building, testing, packaging, and releasing Kubernetes platform software.
Integrate with Kubernetes networking, storage, ingress, certificates, scheduling, security, and cluster lifecycle capabilities.
Contribute to automation using Helm, Terraform, GitOps, Argo CD, Flux, and related tooling.
Implement secure defaults, least-privilege RBAC, secrets handling, workload isolation, and operational guardrails.
Build observable and supportable software using logs, metrics, events, health checks, and status conditions.
Troubleshoot Kubernetes workloads, controller behaviour, failed reconciliations, deployments, and automation issues.
Collaborate with engineering, SRE, security, and application teams, and contribute to documentation, runbooks, and knowledge sharing.

Experience & Qualifications

3+ years of experience in software engineering, platform engineering, DevOps, infrastructure automation, cloud engineering, or SRE.
Experience developing in Go, or strong software engineering experience with the ability to work in Go.
Practical experience with Kubernetes, containers, Linux, and cloud-native deployment patterns.
Familiarity with Kubernetes APIs, CRDs, controllers, reconciliation loops, RBAC, events, status conditions, and resource lifecycle.
